That is not bad but there is only one good way, just buy an all-in-one laser copier with ADF scanner.
C, doing more and more of these sketches is the best way to get it all in your fingers. Keep learning from every sketch, never let it become routine. Mainly what I would advise now is that you work on the communicative value of your sketches, not just seeing them as tools to explore design but as part of a dialogue between all project’s stakeholders. One thing is composition - pre-plan your sketch board to some extent, use groupings, bounding ellipses, some idea for the background, places for arrows and text depending on what you want to communicate.
Also experiment more with variations in perspective, this is all about what the sketch has to communicate.
